The Tower Corner heater is specifically designed to fit seamlessly into tight corners. It makes the most out of a sauna layout without sacrificing heat distribution and the impact of its elegant minimalist aesthetic. It comes with movable steel rings for easy replacement of broken stones, and its removable stone spacer offers two setup options: (1) with the spacer for faster heating, energy efficiency, and a hotter sauna or (2) without the spacer for room to accommodate more stones to generate more steam, a milder temperature, and energy savings in a commercial setup.
